Signal Type
The 150R can detect three types of signals:
•
Active signals that are placed on a target line with a transmitter.
•
An active signal from a beacon.
•
Passive signals that reside on the target line.
Active
There are three ways to place active signals on a target line with a transmitter:
•
Direct connection (preferred method) requires a connection to be made directly onto target line.
•
Induction requires placing an optional induction clamp around target line.
•
Broadcast method uses a built-in antenna to broadcast a signal onto lines near the transmitter.
Beacon
Beacon signals allow metallic and non-metallic pipe or conduit tracing.
Passive
Power line signals can be detected passively without a transmitter.
Receiver Gain Level
The receiver gain setting controls the sensitivity to the signal.
Action
Result
Effect
increasing gain
more sensitive to signal
allows location farther away from
signal source
decreasing gain
less sensitive to signal
stabilizes signal
